This application claims the benefit of U.S. Provisional Application No.61/612,203, filed Mar. 16, 2012, U.S. application Ser. No. 13/466,860,filed May 8, 2012, and U.S. application Ser. No. 13/633,832, filed Oct.2, 2012, the contents of which are hereby incorporated by reference intheir entireties.

BACKGROUND OF THE INVENTION

High ethanol content sanitizer gel is known to be a very effectivetopical antimicrobial agent for preventing infections. Directapplication to bacterial, fungal, and viral organisms in the laboratorysetting results in 99.99% killing within 15 seconds of contact. Thisefficacy is due to its concentration of ethyl alcohol greater than, orequal to, 60% (Federal Register, Vol. 59, No. 116, Jun. 17, 1994).Similar antiseptic activity has been observed for isopropanol (FederalRegister, Vol. 47, No. 99, May 21, 1982). In current commercialformulations, the ethanol containing gel typically contains specialmoisturizers to control dryness on users' hands so they tolerate such ahigh concentration of ethyl alcohol. However, use of these gelscontaining greater than, or equal to, 60% ethyl alcohol on skin damagedwith cracks, tears and/or fissures results in a pronounced stingingsensation (Guideline for Hand Hygiene in Health-care Settings, Centersfor Disease Control.

BRIEF DESCRIPTION OF THE DRAWINGS

The novel features of the invention are set forth with particularity inthe appended claims. A better understanding of the features andadvantages of the present invention will be obtained by reference to thefollowing detailed description that sets forth illustrative embodiments,in which the principles of the invention are utilized, and theaccompanying drawings of which:

FIG. 1 provides a summary of the effect on treatment outcome of themethod of preparation of the matrices and compositions provided hereinas described in example 2-18.

DETAILED DESCRIPTION OF THE INVENTION

New treatments are needed for many dermatologic diseases because currenttreatments lack efficacy, exhibit side effects, or are so unpleasant touse that patients are discouraged from using them. In a series ofclinical trials it has been found that, in comparison to currenttreatments, use of the compositions described herein produces clinicaloutcomes characterized by equal or higher efficacy, while exhibitingminimal side effects and good patient compliance.

It has been discovered that certain topical compositions (lotions,creams, ointments, emulsions and dispersions) that contain ethanol orcertain other alcohols distributed non-homogenously have the unexpectedbenefit of effectively treating a variety of dermatologic diseases anddisorders. Whereas previously known only for maintaining hygiene onhealthy skin, now it is possible to use topical compositions containingethanol or certain other alcohols to treat diseases and disorders of theskin wherein the skin is damaged, broken, torn, or marked by fissures.These skin diseases and disorders range from infections (bacterial orfungal) to inflammatory diseases (dermatitis, psoriasis, acne vulgaris,or rosacea). It has been also discovered that the topical compositionsdescribed herein can be safely used on the face. Effective treatmentsare achieved, in some cases, through use of the topical compositionsdescribed herein wherein ethanol or another alcohol is the sole activeingredient. Further advantages are obtained by incorporating into saidcompositions at least one additional therapeutic active agent. Onedistinguishing feature of these compositions is the non-homogenousnature of the formulation. In particular, it has been found that whenthe ethanol or other alcohol is distributed in a non-homogenous fashionthroughout the composition into bubble-like regions of locally highconcentration, where the approximate effective concentration of theethanol or other alcohol in the bubble-like regions is about 60% toabout 80%, a beneficial effect is observed upon topical application todamaged skin but without a stinging sensation. This result is strikingwhen compared to the well-known stinging sensation observed uponapplication of commercially available high ethanol content sanitizersgels to damaged skin.

Definitions

As used herein, amelioration of the symptoms of a particular disease,disorder or condition by administration of a particular compound orpharmaceutical composition refers to any lessening of severity, delay inonset, slowing of progression, or shortening of duration, whetherpermanent or temporary, lasting or transient that can be attributed toor associated with administration of the compound or composition.

The terms “treat,” “treating” or “treatment,” as used herein, includealleviating, abating or ameliorating a disease or condition symptoms,preventing additional symptoms, ameliorating or preventing theunderlying metabolic causes of symptoms, inhibiting the disease orcondition, e.g., arresting the development of the disease or condition,relieving the disease or condition, causing regression of the disease orcondition, relieving a condition caused by the disease or condition, orstopping the symptoms of the disease or condition eitherprophylactically and/or therapeutically.

The term “comedogenic” describes the tendency of some dermatologicalproducts, such as oils, lotions, ointments, creams, and gels to blockthe pores of the skin. Noncomedogenic products are less likely to clogpores and lead to formation of blackheads (open comedones), whiteheads(closed comedones), red bumps (inflammatory papules) and red, swollen,pussy red bumps and lumps (inflammatory pustules, nodules, and cysts) inpatients' skin. Comedogenic ingredients of many commercially availableskin care products include isopropyl myristate, cocoa butter, coconutoils, and wheat germ oil.

The term “subjective irritation” describes burning, stinging, or itchingwithout detectable visible or microscopic changes in the skin.

The term “non-homogeneous” describes the lack of a uniform phasethroughout the bulk, or entirety, of the composition.

The term “high ethanol content” describes a composition comprisingthroughout the bulk or entirety of the composition, greater than orequal to 60% ethyl alcohol content. Commercially available handsanitizer gels are one example of a high ethanol content composition(Federal Register, Vol. 59, No. 116, Jun. 17, 1994).

The term “standardized topical corticosteroid concentration” means, fora particular corticosteroid, the United States Food and DrugAdministration (US FDA) approved concentration for topical use. Thestandardized topical corticosteroid concentrations are provided in theUnited States Pharmacopeia, which is hereby incorporated by reference inits entirety. For some corticosteroids, there is more than onestandardized topical corticosteroid concentrations approved for use bythe US FDA due to factors such as different form of formulation (forexample, cream vs. ointment) and the like.

Skin Diseases and Disorders

Acne Vulgaris (“Teenage Acne”)

Acne is a common skin disease that affects 60-70% of Americans at sometime during their lives. In some embodiments teenagers need ongoingtreatment from age 12 to 23 years old.

Acne vulgaris is characterized by the onset around puberty of comedonesand inflammatory lesions on the face, neck, chest, and back. It tends toresolve on average around age 23 years of age. The pathogenesis ismultifactorial. There is increased oil production by increasingly activeskin oil glands under the influence of puberty associated hormones. Anobstruction of the secretory tubules (“pores”) which connect the glandto the skin surface leads to accumulation of oil under the skin surface.As the volume increases the lumps called comedones become visible.Bacteria then proliferate in the oil leading to further inflammation inthe skin causing the formation of the visible red papules, pustules,nodules, and cysts typically seen in acne vulgaris. The specificbacteria infecting these lesions has been identified asProprionobacterium acnes. These lesions can be uncomfortable or tender,can create disfigurement of the teenager compared to his peers, leadingto embarrassment in affected boys and girls. Thus teenagers frequentlyseek treatment to minimize this disorder.

Treatment is based on agents which seek to correct the fundamentalpathologic events creating acne lesions.

Topical treatments fall into several classes:

a) “Comedolytic agents” dissolve the secretory tubule obstruction thusallowing drainage of the trapped oil. Topical agents of this typeinclude: sulfur, resorcinol, salicyclic acid, glycolic acid, retinoidssuch as tretinoin, adapaline and tazarotene, and benzoyl peroxide.

b) “Antibacterial agents” suppress the bacterial population. Topicalagents of this class include: benzoyl peroxide, antibiotics(erythromycin, clindamycin), and astringents, and nonspecific mechanismagents like azelaic acid.

c) “Cleansers” seek to dissolve surface oil, dissolve clogged pores, andremove bacteria. Oral treatments: These include oral antibiotics(tetracycline family, erythromycin macrolide family, ampicillinpenicillin family) which suppress the bacteria. The oral agent13-cis-retinoic acid (Accutane™) seeks to reduce oil production andresolve clogging of the pores.

In some embodiments, the compositions and methods described herein areuseful for the treatment of acne vulgaris. In some embodiments, thecompositions and methods described herein are an excellent first linetreatment for mild to moderate, and some cases, severe pustular acneseen in teenagers. The compositions and methods described herein areoptionally used independently, or in combination with over-the-counterand/or prescription dispensed therapeutically active agents to addressall types of acne lesions. In some embodiments, the compositionsdisclosed herein include at least one comedolytic agent. In someembodiments, the compositions disclosed herein include at least oneanti-inflammatory agent. In some embodiments, the compositions disclosedherein include at least one antibiotic agent.

Rosacea (“Adult Acne”)

In this disorder, adults, usually 25 years and older, develop a triad ofdistinctive features separating it from acne vulgaris (“teenage acne”).The triad consists of:

-   a) central facial increased redness and increased surface blood    vessels;-   b) central facial inflammatory red papules, pustules, and nodules;-   c) tendency to easy facial flushing and blushing in response to    trigger factors including certain psychological states    (embarrassment or anger), exercise during workouts, consumption of    alcoholic drinks and hot coffee/tea.

The condition can last for many years and gradually worsen. Patients areusually motivated to seek treatment because of the disfigurement of theskin disorder.

In a recent study, Dr. Maeve McAleer and colleagues at the School ofPublic Health and Population Science, University College, Dublin, foundthat 14.4 percent of 1,000 subjects examined in Ireland had rosacea.Moreover, in a 1989 study of 800 office workers in Sweden, theprevalence of rosacea was 10 percent—including 14 percent in women and 6percent in men.

The specific pathogenesis of rosacea is not known. The same bacteriafound infecting acne vulgaris lesions has not been found in rosacea.There are no plugged up pores (comedones) present in rosacea patients.There are many hypotheses for rosacea causation revolving around apostulated bacteria which infects the skin leading to the inflammationso characteristic of the condition.

Treatment of rosacea involves the use of topical and oral agents.

Topical Agents:

-   a) Antimicrobial agents: metronidazole, sulfa/sulfur combinations,    clindamycin, benzoyl peroxide;-   b) Anti-inflammatory agents of uncertain mechanism: azelaic acid.    Oral Agents:-   a) Antibacterial agents: These include oral antibiotics    (tetracycline family, erythromycin macrolide family, ampicillin    penicillin family) which suppress growth of bacteria and/or kill    bacteria.

Use of the compositions and methods described herein is a very effectivetopical treatment for red bumps and pussy bumps of rosacea. Thetreatment produces clinical improvement noticeable to the patientswithin a week of starting treatment. Of equal significance is that thistreatment rapidly reduces central facial redness. This is not true oftopical Finacea™ or Metrogel™ which are the current standard of care forthis indication. Advantages of the compositions and methods disclosedherein for the treatment of rosacea over current topical treatments,such as Finacea and Metrogel, include faster onset of relief, reliablyreduces redness, no stinging, less costly, and reduced environmentalimpact. Advantages of the compositions and methods disclosed herein forthe treatment of rosacea over current oral include no concerns aboutsafety of oral antibiotics, no upset stomach or sun sensitizationissues, no impact on use of oral contraceptives, no issue of vaginalyeast infections, and reduced environmental impact. In some embodiments,the compositions and methods described herein are useful for thetreatment of rosacea. In some embodiments the compositions disclosedherein include at least one anti-inflammatory agent. In someembodiments, the compositions disclosed herein include at least oneantibiotic agent.

Dermatitis

Dermatitis, or eczema, is a common, very uncomfortable, frequently veryitchy, rash characterized by red, scaly, patches in the skin. Theredness, swelling, and discharge are all signs of inflammation of anallergic type process. The classification of the dermatitis isdetermined by the appearance and distribution of the patches and thedemographics of the patient. For example, atopic dermatitis ischaracterized by rash patches located typically in the fronts of theelbows and behind the knees in young children. Nummular dermatitis ischaracterized by round rash patches scattered randomly on the trunk andlimbs of adults. Contact dermatitis is characterized by linear shapedswollen patches on the trunk or limbs at any age.

Prior to the discovery of the methods, compositions and devicesdisclosed herein, the use of high ethanol content gels in the treatmentof eczema was complicated by a stinging sensation upon topicalapplication. This stinging occurs because the acute phase of the rash ischaracterized by many small cracks and fissures in the skin. By usingthe methods, compositions and devices disclosed herein to treat theacute phase of eczematous lesions topical application of the compositiondoes not cause a stinging sensation. Maintenance therapy employing themethods, compositions and devices disclosed herein to suppress therecurrence of eczematous lesions is provided by application of thecomposition, such that topical application of the composition does notcause a stinging sensation.

During the sub-acute phase (rash but no fissures) the compositiondisclosed herein is well tolerated and increases efficacy of concomitantor subsequent topical steroid therapy in resolving the remaining rash.Once the eczema is resolved, ongoing use of the compositions asdisclosed herein that do not contain corticosteroid helps sustain thedisease-free remission period. The addition of moisturizing ingredientsto the compositions disclosed herein keep the skin moist.

In some embodiments, the compositions and methods described herein areuseful for the treatment of dermatitis. In some embodiments thecompositions disclosed herein include at least one anti-inflammatoryagent.

Atopic Dermatitis

Atopic dermatitis occurs in approximately 10-20% of children and 2% ofadults (Ong P Y, Leung D Y. Immune dysregulation in atopic dermatitis.Curr Allergy Asthma Rep. September 2006; 6(5):384-9).

In the developed countries of North America and Europe, children fromages 2 to 8 years commonly suffer from this itching, unattractive rash.The discomfort and sleep deprivation are a major burden for patients andtheir families.

Treatment of eczema is difficult and often requires a multi-facetedapproach. Moisturizers are administered to relieve dry skin. Coldcompresses can relieve itch. Corticosteroid and topical calcineurininhibitors can reduce inflammation. Antibiotics treat bacterialinfection. Sedative antihistamines can enable sleep and rest. Formoderate to severe cases, phototherapy can be used.

The latest scientific understanding of the causes of eczema highlightthe unmet medical need satisfied by the methods, compositions anddevices disclosed herein. In patients with eczema, the skin is drierthan usual with outer layer cracks and fissures which facilitate easycolonization by a particular bacterium, Staphylococcus aureus(Boguniewicz M, Leung D Y M. Atopic dermatitis: a disease of alteredskin barrier and immune dysregulation. Immunolog Rev. 2011; 24:233-46).The staphylococcal population density in the skin rises greatly becausethe patients are deficient in some of the usual factors required todefend against them (Miajlovic H, Fallon P G, Irvine A D, Foster T J.Effect of filaggrin breakdown products on growth of and proteinexpression by Staphylococcus aureus. J. Allergy Clin. Immunol. 2010;126:1184-1190; Cho S-H, Strickland I, Boguniewicz M, et. al. Fibronectinand fibrinogen contributes to the enhanced binding of S. aureus toatopic skin. J. Allergy Clin. Immunol. 2001; 108:269-74; Bunikowski R,Mielke M, Skarabis H, et al. Prevalence and role of serum IgE antibodiesto the Staphylococcus aureus-derived superantigens SEA and SEB inchildren with atopic dermatitis. J. Allergy Clin. Immunol. 1999;103:119-24; Leung D Y M, Harbeck R, Bina P, et al. Presence of IgEantibodies to staphylococcal exotoxins on the skin of patients withatopic dermatitis: evidence for a new group of allergens. J. Clin.Invest. 1993; 92:1374-80; Zollner T M, Wichelhaus T A, Hartung A, et al.Colonization with superantigen-producing Staphylococcus aureus isassociated with increased severity of atopic dermatitis. Clin. Exp.Allergy 2000; 30: 994-1000). The staphylococci worsen the eczema by animmune mechanism which up-regulates inflammation culminating in thesymptoms and appearance of the visible eczema rash (Reginald K,Westritschnig K, Linhard B, Focke-Tejkl M, et. al. Staphylococcus aureusfibronectin-binding protein specifically binds IgE from patients withatopic dermatitis and requires antigen presentation for cellular immuneresponses. J. Allergy Clin. Immunol. 2011; 128:82-91).

Measures which decrease this bacterial population are generally found tohelp resolve eczema. Oral and topical antibiotics currently are used forthis purpose. Previously, high ethanol content gels were to be avoideddue to the stinging sensation upon topical application as the stingingsensation would lead to a lack of patient compliance.

While the use of “bleach baths” has recently been shown to improveeczema by lowering the S. aureus skin population (Huang J T, Abrams M,Tlougan B, Rademaker A, Paller A S. Treatment of staphylococcus aureuscolonization in atopic dermatitis decreases disease severity. PediatricsMay 2009; 123(5): 808-814) caregivers are reluctant to use thistreatment because of the time and effort required. This effort includespreparing the bath, cleaning up afterwards, ventilating the bathroom toremove the bleach odor, and trying to avoid bleaching bathroom linens.

Use of the compositions as described herein is a significant advance fortopical therapy in eczema. Caregivers find applying the compositionsdescribed herein to be an easy and familiar way of treating skinproblems.

Secondarily Infected Dermatitis

Due to the marked itchiness of rashes, dermatitis patients frequentlyscratch the affected skin disrupting its integrity and providing a“portal of entry” for bacteria to infect the skin. Thus a rash whichbegan with only inflammation soon becomes so called “secondarily”infected with bacteria. This colonization of the rash with an overgrowthof abnormal bacteria (often Staphylococcus aureus) further contributesto skin irritation. Thus, because a secondary infection has occurred,effective treatment of the rash must suppress both inflammation andinfection.

Treatment of dermatitis employs several classes of therapeutic agents.

Topical Treatment:

-   a) Immunosuppressive agents to reduce inflammation include    corticosteroids such as hydrocortisone and many other related    molecules, and immunomodulating agents such as tacrolimus and    pimecrolimus.-   b) Antibacterial agents to suppress bacterial infection include    mupirocin, retapamulin, neomycin, bacitractin, polymyxin, and sulfa.    Oral Treatment:-   a) Immunosuppressive agents to reduce inflammation include    corticosteroids like prednisone-   b) Antibiotics to suppress bacterial infection include tetracycline    family, erythromycin macrolide family, penicillin family,    cephalosporin family, ciprofloxacin family, and clindamycin.-   c) oral antihistamines to reduce the itch and swelling of    inflammation.

Use of compositions as described herein dramatically improves theefficacy of topical steroids while eliminating the need for topical andoral antibiotics. This simpler treatment means better compliance andbetter success in treatment.

Athlete's Foot (Tinea Pedis)

Tinea pedis is thought to be the world's most common dermatophytosis.Reportedly, 70% of the population will be infected with tinea pedis atsome time.

In this fungal infection of the soles, there are dry pink to tan scalypatches which gradually expand to cover the sole and the web spacesbetween the toes. Often cracks occur due to the dryness causingdecreased skin flexibility. Symptoms often range from mild to severeitching from the inflammation of the skin and mild to severe discomfortdue to the cracks. Typically it begins in teen years and can lastthrough adulthood. Sometimes painful blisters can occur due to theintense inflammation induced by the immune defense response to thefungal infection.

Current standard of treatment includes administration of topical agentsand/or the use of oral agents. Topical treatment include antifungalagents such as terbenafine, econazole, miconazole, clotrimazole,butenafine, tolnaftate, or salicylic acid. All of these agents typicallytake 2-4 weeks to improve the rash. Oral agents used for the treatmentof tinea pedis include griseofulvin, terbenafine, itraconazole, orfluconazole.

Psoriasis

According to the National Institutes of Health (NIH), approximately 2.2%of the United States population have psoriasis.

Psoriasis is characterized by red scaly elevated plaques which are oftenlocated on elbows and knees but can be extensively spread out on theskin of the trunk, limbs, and scalp. This is a chronic, often recurrent,condition which usually begins in early adulthood and lasts thelifetime. Sometimes children are affected. The rash can beuncomfortable, unsightly, and embarrassing.

The pathogenesis of psoriasis is not well understood. Currentunderstanding suggests immune system activation leading to inflammatorychanges in the skin. Current methods of treatment seek to reverse theinflammatory changes and reduce the overgrowth thickening of theaffected skin areas.

Topical treatment includes use of anti-inflammatory agents (such ascorticosteroids to reduce the inflammation in the skin) andantiproliferative agents (such as calcipotriene to reduce the skinovergrowth). Topical agents often have limited effectiveness due toinadequate percutaneous drug delivery through the thickened psoriaticskin. To overcome this obstacle, a topical agent can be covered overwith an air impermeable plastic sheet (Saran Wrap™) to increasepercutaneous drug delivery. While effective, it is very uncomfortable towear leading to poor compliance and thus inadequate efficacy.

Oral or systemic agents include anti-inflammatory agents (such asmethotrexate, or cyclosporine), and tumor necrosis factor inhibitors(etenercept, infliximab, and similar others). While effective they candamage blood and liver and pose risks of severe toxicity includingdeath. Other modes of therapy include ultraviolet light treatment tosuppress epidermal growth (however, one drawback of this treatment isthe potential to cause cancer of the skin) and corticosteroid injectionsinto patch suppresses inflammation locally (this is very uncomfortableand can lead to unsightly thinning where injected).

In some embodiments, the compositions and methods described herein areuseful for the treatment of psoriasis. In some embodiments thecompositions disclosed herein include at least one anti-inflammatoryagent. In some embodiments the compositions disclosed herein include atleast one anti-proliferative agent.

Test for Stinging

An assessment of stinging can be made using a superficial skin abrasionmodel. When the skin is disrupted by superficial wounds, subsequentlyapplied materials can sting, burn, and irritate. To measure thestinging, standardized wounds can be created in the skin, typically onthe forearm, by sequential tape stripping repeated until the glisteninglayer is reached. This glistening layer corresponds to the skin's dermallayer where nerves are located. Materials to be tested on thesuperficial wounds would include a positive control material, such 70%ethanol solution, a negative control, such as the formulation vehiclewithout active agents, and the test formulation(s). Each material isapplied to a single site on the abraded forearm for a short duration oftime, such as 15 seconds. The study subject is then asked to rate theintensity of stinging/burning using a predesignated multi-point scale.Thus, stinging as well as burning sensations can be assessed by thismethod.

For example, in a study of novel first aid formulation for wounds,standardized wounds were created by sequential tape stripping repeateduntil the glistening layer was reached (Pagnoni A, Spinelli G, Berger RS, Bowman J, Garreffa S, Snoddy A M. Lack of burning and stinging from anovel first aid formulation applied to experimental wounds. J. Cosmet.Sci. March-April 2004; 55(2):157-62). Each material to be tested wasapplied to a wound for 15 seconds. The 24 subjects in the study reportedthe intensity of the stinging/burning sensation. The tested materialsincluded 70% isopropyl alcohol (sting/burn control), sterile 0.9% sodiumchloride solution (no sting/no burn control) and the novel formulation.It was found that the alcohol stung while the novel formulation stung nomore than the saline solution.

In another example, irritation of superficial wounds by topical agentscommonly used in wound care was assessed using this superficial skinabrasion model (Trookman N S, Rizer R L, Weber T. J. Amer. Acad.Dermatol. March 2011; 64(3), Suppl 1:S16-22). As in the previousexample, the skin was prepared by sequential tape stripping prior totopical application of the materials in the study.

The Coopman classification is particularly useful in cases where acertain corticosteroid serves an allergen. In this situation allergicreactions to one member of a class typically indicate an intolerance ofall members of the class.

An alternative classification protocol involves grouping by strength inan standard vasoconstriction assay (Ference and Last, Am Fam Physician.2009, Jan. 15; 79(2):135-140). In this protocol, seven potency groupshave been established ranging from high potency to low potency.

Ultra high (I) Augmented betamethasone dipropionate 0.05% Clobetasolpropionate 0.05% Diflorasone diacetate 0.05% Fluocinonide 0.1%Flurandrenolide 0.05% High (II) Amcinonide 0.1% Augmented betamethasonedipropionate 0.05% Betamethasone dipropionate 0.05% Desoximetasone 0.25%Diflorasone diacetate 0.05% Fluocinonide 0.05% Halcinonide 0.1%Halobetasol propionate 0.05% Medium to high (III) Amcinonide 0.1%Betamethasone dipropionate 0.05% Fluticasone propionate 0.005%Triamcinolone acetonide 0.5% Halobetasol propionate 0.05% Medium (IV andV) Betamethasone valerate 0.1% Desoximetasone 0.05% Fluocinoloneacetonide 0.025% Fluticasone propionate 0.05% Hydrocortisone butyrate0.1% Hydrocortisone probutate 0.1% Hydrocortisone valerate 0.2%Mometasone furoate 0.1% Triamcinolone acetonide 0.025% Triamcinoloneacetonide 0.1% Low (VI) Alclometasone dipropionate 0.05% Desonide 0.05%Fluocinolone 0.01% Hydrocortisone butyrate 0.1% Least potent (VII)Hydrocortisone 1%, 2.5%

Ultra-high-potency topical steroids should not be used continuously forlonger than three weeks. Low- to high-potency topical steroids shouldnot be used continuously for longer than three months to avoid sideeffects. Prolonged use of topical corticosteroids may cause sideeffects. To reduce the risk, the least potent steroid should be used forthe shortest time, while still maintaining effectiveness.

In addition to allowing for the use of an antiseptic alcohol, such asethanol, 1-propanol, or 2-propanol, in a manner which avoids stingingwhen applied to cracked or damaged skin, the compositions and methodsdescribed herein allow for the use of corticosteroids at lowerconcentrations than previously employed while maintaining efficacy. Thebenefits derived from this treatment regimen at lower doses ofcorticosteroid are several. First, a lower dose or exposure level ofcorticosteroid will result in fewer side effects from corticosteroiduse. Second, if lower doses or exposure levels are possible, theattending physician optionally elects to use a more potentcorticosteroid for difficult to treat cases. Also, the use of the morepotent corticosteroid allows for faster resolution of dermatologicalcondition and an overall shortening of the period of time during whichthe patient is undergoing therapy. Thus, one advantage of thecompositions and methods described herein is that the compositionsdescribed herein provide equal or greater efficacy than currentlyaccepted treatments but at a lower exposure level of corticosteroid tothe patient.

II. Treatment of Skin Diseases and Disorders Example 2-1 Treatment ofSecondarily Infected Dermatitis

Dermatitis is a common form of red, scaly, itchy patches whichfrequently is infected due to the patients scratching their itchy areas.Conventional treatment is based on use of topical steroid creams, andoral or topical antibiotics. Treatment often is only partly helpful andpatients often are reluctant to use oral antibiotics due to potentialside effects. Several patients have presented with secondarily infecteddermatitis and participated in the new course of treatment.

-   -   a. Man with hand dermatitis. Treatment with topical mometasone        cream and oral antibiotics and topical mupirocin provided        partial response over 3 weeks treatment. In an attempt to        achieve complete response the patient was treated with a        non-homogenous composition comprising mometasone (0.05%) and        ethanol (31%); no further oral antibiotics were administered.        The patient showed significant improvement in 3 days.    -   b. Man with Extensive Dermatitis Over his Trunk and Limbs with        Culture Proven staphylococcus aureus. Treatment with a        non-homogenous composition comprising ethanol (31%) and        triamcinolone (0.05%) was far more effective than oral        antibiotic therapy (cephalexin) combined with triamcinolone        (0.1%) cream. Within 2 days the patient showed significant        improvement.    -   c. Woman with 20 Years of Hand Dermatitis Complicating        Scleroderma (a Form of Skin Tightening which Compromises Blood        Flow). The patient reported 75% clearing of her condition within        3 days of starting a treatment with a non-homogenous composition        comprising ethanol (31%) and clobetasol (0.025%). The patient's        chronic condition had failed to respond to oral antibiotics,        topical antibiotics, topical cortisones including clobetasol        cream. This treatment with a non-homogenous composition        comprising ethanol (31%) and clobetasol (0.025%) worked when        clobetasol cream under plastic (glove occlusion) and cortisone        tape had failed.

An 11 year old girl presented with recurrent persistent eczema onlypartly improved on the combined use of mometasone ointment and oralantibiotics. Within a week of starting a treatment with a non-homogenouscomposition comprising ethanol (31%) and mometasone (0.05%) thepatient's condition was 85% clear.

Example 2-3 Treatment of Facial Eczema

Twenty-six patients with facial eczema were treated for two weeks twicedaily with a non-homogenous ointment consisting of desonide 0.05%ointment mixed with 62% ethanol gel. The non-homogenous ointment wasused in fixed ratios ranging from 10:1 to 1:1 (desonide ointment/ethanolgel), or as part of a progressive ratio therapy in which the initialratio was 5:1 (desonide ointment/ethanol gel) and the ratio was changedevery 2 days to 3:1, then 2:1 and ending at 1:1. Each preparation wasprepared immediately prior to application. Results from all 26 patientsare displayed in Table 2-1. Results from nine patients who used fixedratios of desonide ointment/ethanol gel are displayed in Table 2-2.Results from 17 patients who underwent progressive ratio therapy aredisplayed in Table 2-3.

Example 2-7 Comparison of the Results of Clinical Trials for TreatingEczema in Children with Corticosteroid/Ethanol Non-homogenousComposition Versus Published Results for Using Conventional Treatment

1) Topical Mometasone/Ethanol Prototype Compared to “Bleach Baths” inTreating Children with Eczema.

A recent study (Huang J T, Abrams M, Tlougan B, Rademaker A, Paller A S.Treatment of staphylococcus aureus colonization in atopic dermatitisdecreases disease severity. Pediatrics May 2009; 123(5): 808-814)evaluated a new method for treating eczema employing “bleach baths” totopical corticosteroid treatment as a means to suppress thestaphylococcal population on the skin. This bleach bath-topicalcorticosteroid treatment resulted in a mean improvement of 40% in 1month of use. These results were inferior to twice daily treatment ofprototype non-homogenous ointment consisting of mometasone furoate 0.1%ointment mixed with 62% ethanol gel in fixed or progressive ratios,which resulted in a mean improvement of 90% in two weeks (data presentedin Table 2-4).

2) Topical Desonide/Ethanol Non-homogenous Composition Compared toConventional Desonide Formulations in Treating Children with Eczema.

The use of commercially available desonide formulations in treatingchildren with eczema has been reported in the literature. Desonide 0.05%hydrogel and desonide 0.05% ointment provided 25% and 34% success,respectively, after 2 weeks of therapy and 25% and 52% success,respectively, after 3-6 weeks of therapy (Trookman N S, Rizer R L.Randomized Controlled Trial of Desonide Hydrogel 0.05% versus DesonideOintment 0.05% in the Treatment of Mild-to-moderate Atopic Dermatitis. JClin Aesthet Dermatol. November 2011; 4(11): 34-38). Another studyshowed that desonide 0.05% hydrogel and its hydrogel vehicle provided19% and 3% success, respectively, after 2 weeks of therapy and 39% and11% success, respectively, after 3-6 weeks of therapy (Hebert A A,Cook-Bolden F E, Basu S, Calvarese B, Trancik R J. Safety and efficacyof desonide hydrogel 0.05% in pediatric subjects with atopic dermatitis.J Drugs Dermatol. February 2007; 6(2):175-81). In these two studies, thedesonide hydrogel contains propylene glycol in its vehicle and thedesonide ointment contains no alcohol. In sharp contrast, prototypenon-homogenous ointment consisting of a mixture of desonide/ethanol infixed or progressive ratios led to 88% success after two weeks of twicedaily treatment (data shown in Table 2-1). The prototype non-homogenousointment provided better results in a shorter period of time. In allstudies, success was defined as the percentage of patients that achieved75% or better improvement compared to baseline.

3) Topical Mometasone/Ethanol Non-homogenous Composition Compared toConventional Mometasone Cream in Treating Children with Eczema.

The use of commercially available mometasone formulations for thetreatment of children with eczema has been reported in the literature.One study found that mometasone 0.1% cream provided 50% success after 3weeks of therapy (Rafanelli A, Rafanelli S, Stanganelli I, et. al.Mometasone furoate in the treatment of atopic dermatitis in children. J.Eur. Acad. Dermatol. Venereol. 1993; 2(3):225-230). Another study foundthat mometasone 0.1% cream led to 63% success after 3 weeks of therapy(Vernon H J, Lane A T, Weston W. Comparison of mometasone furoate 0.1%cream and hydrocortisone 1.0% cream in the treatment of childhood atopicdermatitis. J. Am. Acad. Dermatol. April 1991; 24:603-7). A third studyreported overall results similar to the other two studies (Lebwohl M,Lane A T, Berman B, et. al. Efficacy and safety of 0.1% mometasonefuroate cream versus 0.2% hydrocortisone valerate cream in pediatricpatients with atopic dermatitis un-responsive to topical hydrocortisonetreatment. Proceedings of the 55^(th) Annual Meeting of the AmericanAcademy of Dermatology Mar. 21-26, 1997; abstract number P-43). In allcases, the mometasone 0.1% cream included propylene glycol stearate (55%monoester) in its vehicle. Use of the prototype non-homogenous ointmentconsisting of a mixture of mometasone/ethanol in fixed or progressiveratios provided 98% success after only two weeks of twice dailytreatment (data in Table 2-4). In all studies, success was defined aspercentage of patients achieving 75% or better improvement compared tobaseline.

Example 2-8 Clinical Trial of Moisturizer/Ethanol Non-homogenousComposition in Preventing Recurrence of Eczema

Demographics: 7 patients with chronic recurrent eczema entered thetrial. Prior to starting the trial all had cleared their eczema rashusing rash treatment prototype topical therapy. All had a past historyof conventional moisturizers failing to prevent recurrence of eczemawithin 10 days of stopping prior rash therapy.

Protocol: All used maintenance non-homogenous lotion twice a day.

Materials: The maintenance non-homogenous lotion was Cetaphil™moisturizing lotion mixed in a ratio of 1:1 with 62% ethanol gelimmediately before application.

Duration of follow-up:

-   -   a. 1 month: 2 patients    -   b. 1.5 months: 1 patient    -   c. 2 months: 2 patients    -   d. 6 months: 1 patient    -   e. 7 months: 1 patient

Outcome of Protocol Treatment: 6 of the 7 patients reported they stayedentirely clear while on consistent use maintenance therapy. One patientreported when the weather got very cold and dry, the rash recurreddespite the maintenance therapy.

Conclusion

The maintenance prototype was strikingly effective in maintainingpatients rash-free.

Example 2-9 Two Case Studies Demonstrating Killing or Inhibition of S.Aureus Growth Using Corticosteroid/Ethanol Non-homogenous Compositions

Case 1: A 26-year old man with eczema on the hand was treated twicedaily for three days with a mixture of triamcinolone 0.1% ointment in a5:1 ratio with 62% ethanol gel. The pre-treatment bacterial culture fromthe eczematous rash reported growth of S. aureus. The post-treatmentbacterial culture performed after three days of treatment showed no S.aureus present.

Case 2: A 92-year old man with eczema on the hand was treated twicedaily for seven days with a mixture of fluocinolone 0.1% ointment in a1:1 ratio with 62% ethanol gel. The pre-treatment bacterial culture fromthe eczematous rash reported growth of S. aureus. The post-treatmentbacterial culture performed after seven days of treatment showed no S.aureus present.

Example 2-10 Non-Stinging Test Using Superficial Skin Abrasion Model

In a study with 20 subjects, this test is performed on a total of 6sites on each subject: three test sites on each arm. Tape is used tosequentially strip the skin until the glistening layer is visible. Thetest materials include a positive stinging control (70% ethanolsolution), a negative stinging control (formulation vehicle withoutethanol) and the novel formulation with ethanol (with or without asecond active agent). Each material is applied to a single site on eachforearm to allow for a separate determination of response consistency.Each material is applied for 15 seconds to each site. Each subjectreports the intensity of the stinging/burning sensation on a 0-4 pointscale. The outcome of the study is determined by comparing the scores ofall the sites.

Example 2-11 Treatment of Tinea Versicolor

Tinea versicolor is a rash in humans known to be caused by two speciesof malassezia: malassezia globosa and malassezia furfur.

The patient was a 39 year old man with a two-year history of extensivetan moderately scaling patches symmetrically on the chest and back.Condition failed to respond to a month of conventional treatment withzinc pyrithione lotion. The diagnosis was confirmed by a KOH microscopicexamination of a specimen from the back rash showing very large numbersof short fat hyphae and round yeasts.

Treatment of once daily application of 70% ethanol gel to affected areasfor two weeks was begun. The patient reported that the treatment waswell tolerated and comfortable to perform.

The course of treatment resulted in the back patches post-treatmentshowing 10% of the pretreatment scaling. KOH microscopic examination ofthe rash done post treatment showed complete absence of hyphae and roundyeast. The chest patches post treatment had 25% of pretreatment scaling.The KOH microscopic examination of the specimen post treatment showedrare short fat hyphae and no round yeasts.

Conclusions: Ethanol killed malassezia genus organisms in this in vivotherapeutic trial. The patient demonstrated improvement in the rash bothas measured by clinical examination and microscopic assessment.

Example 2-12 Treatment of Seborrheic Dermatitis

The patient was a 79-year old man with a prolonged, multi-year historyof facial seborrheic dermatitis which failed to respond adequately toeither a low potency prescription corticosteroid cream (hydrocortisonevalerate 0.2%), or to a mid-potency corticosteroid cream (mometasone0.1%) in combination with an anti-fungal cream (ketoconazole cream). Ina trial of the compositions described herein, he applied twice a day for6 days a non-homogenous 10:1 mixture of hydrocortisone butyrate cream0.1% (10 parts) and 62% ethanol gel (1 part). This course of therapyresulted in 100% clearing of the facial areas treated and was welltolerated. The patient reported he had never cleared this much, or thisfast, from any of the prior therapies.

Example 2-13 Treatment of eczema

A chemical matrix for the treatment of eczema using triamcinaloneacetonide and ethanol was prepared as described in Example 1-3 using thefollowing ingredients:

-   2.5 ml of triamcinalone acetonide cream 0.1%;-   2.5 ml of AQUAPHOR®; and-   1 ml of 62% ethanol gel.    The final concentration of active ingredients in this new chemical    matrix are:-   triamcinalone acetonide 0.042%, and ethanol 10.3%.

A 64-year-old woman presented with extensive, extremely itchy, crustedeczema on the trunk and legs and such a condition had existed for over ayear. The condition persisted despite treatment with triamcinaloneacetonide cream 0.1% used daily for more than 9 months. No improvementwas observed when she covered the areas treated with the triamcinalonecream for 8 hours with wet pajamas. Treatment was begun using the sametriamcinalone acetonide 0.1% cream but now reformulated into thechemical matrix described above. The triamcinalone acetonide and ethanolmatrix was applied twice daily without any wet covering. The patientreported within 24 hours of treatment the itching was greatly reduced.When examined after 1 week of treatment, the former rash was 95%resolved.

Example 2-14 Treatment of Persistent Pediatric Eczema

A chemical matrix for the treatment of eczema using desonide and ethanolwas prepared as described in Example 1-3 using the followingingredients:

-   2.5 ml of desonide ointment 0.05%;-   2.5 ml of AQUAPHOR®; and-   1 ml of 62% ethanol gel.    The final concentration of active ingredients in this new chemical    matrix are:-   desonide 0.021%, and ethanol 10.3%.

An 18-month-old child presented with extensive, extremely itchy, crustedeczema on the face, trunk, arms, and legs persisting for several months,worsening in the preceding 10 days. Treatment with moisturizing creamsand 1% hydrocortisone cream did not resolve the rash. Treatment wasbegun using the desonide and ethanol matrix described above. Thedesonide and ethanol matrix was applied twice daily. The parentsreported the rash was almost entirely resolved at 4 days of treatment.

Example 2-15 Treatment of Persistent Eczema with a FormulationContaining 17% of the Standardized Topical Corticosteroid Concentrationof Mometasone

History:

A 41 year old man presented with infected eczema on his fingers for manyyears. His eczema had persisted despite daily use separately of both atopical corticosteroid and an ethanol gel. He had used triamcinalone0.1% cream twice daily treatment for years without benefit. It alsohappens that for years it has been his custom during the day to applycommercial hand sanitizer gel 5-6 times to his hands for general healthpurposes. The rash persisted despite both these separately appliedtopical agents.Treatment:

A topical formulation was prepared containing 2.5 ml of 70% ethanolbased hand sanitizer gel, 2.5 ml of mometasone ointment 0.1%, and 10 mlof AQUAPHOR®. It was applied twice daily for a week.

Results:

The patient reported that within two days of beginning the new treatmenthe saw marked improvement in his fingers rash. For the first time everhe saw the tiny little blisters in the rash resolve without expanding,draining on the surface and becoming painful. By the end of a week oftreatment he reported almost all the redness, scaling, and itch wasgone. He reported that he had never seen such improvement with the priortreatment.

On examination at one week of treatment there was an 85% improvement inthe rash on the fingers compared to pretreatment.

Conclusion:

This case demonstrates that this formulation containing a suspension ofethanol microbubbles in a corticosteroid ointment was superior to theindependent application of ethanol gel and corticosteroid topical cream.It is also noted that this improvement was achieved with a formulationcontaining 17% of the standardized topical corticosteroid concentrationof mometasone whereas the prior use of cream containing the full 100% ofthe standardized topical corticosteroid concentration of triamcinalonehad failed.

Example 2-18 Effect of Method of Preparation on Treatment Outcome

Clinical outcomes were compared using freshly prepared medication andusing medication which had been prepared and then stored. Treatmentoutcome was determined at the end of 1 or 2 weeks of treatment.

Procedure:

A single use medication was a topical formulation that was preparedimmediately before application and the excess was discarded after oneapplication.

A multi use medication was a topical formulation that was prepared andthen used for a week of twice daily applications. It was stored in anopen-top plastic container which was further placed inside a zip lockplastic bag in a refrigerator between applications. Each week a newbatch was prepared.

Standardized topical corticosteroid concentrations of thecorticosteroids studied:

-   -   Desonide Ung: 0.05%    -   Mometasone Ung: 0.1%    -   TAC Ung 0.1%    -   TAC Cr 0.1%        Procedure for the preparation of the medication:    -   1. The 2.5/2.5/1 medication was prepared by combining 2.5 ml of        the corticosteroid ointment, 2.5 ml of AQUAPHOR® (moisturizer),        and 1 ml of ethanol gel 70%.    -   2. The 10/2.5/2.5 medication was prepared by combining 2.5 ml of        the corticosteroid ointment, 10 ml of AQUAPHOR® (moisturizer),        and 2.5 ml of ethanol gel 70%.

Successful clinical outcome is defined as greater or equal to 75%reduction in eczema rash compared to status pre treatment.

As shown in FIG. 1, successful outcomes were observed for both thesingle and multi use medications. Concentrations as low as 17% of thestandardized topical corticosteroid concentration provided successfuloutcomes.
